In one embodiment, a method includes configuring a first node, located at an edge of a core network and connected to an access ring, with a maintenance end point for a virtual local area network on a port connecting the first node to the access ring. The first node operates in an active mode for the virtual local area network and is in communication with a second node located at the edge of the core network and connected to the access ring. The method further includes receiving and processing at a processor at the first node, continuity check messages from access nodes on the access ring, synchronizing the first node with the second node, and communicating from the first node to the second node to initiate switching of the second node from a backup mode to the active mode for the virtual local area network upon identification of a failure.
